Most awaited device from Apple launched, however the over all improvement do not have any surprise package. We are expecting apple to adding feaatures like multitasking, improve its high defination camara and video recording and full utilisetion of 3G by offering dual camara to utilise cideo chat features too. SDK 4.0 release expecting these key changes.

From developer’s point of view I can say that these features get more opportunity to visulilze and create more creative application.

Apple site says that “The Retina display on iPhone 4 is the sharpest, most vibrant, highest-resolution phone screen ever, with four times the pixel count of previous iPhone models. In fact, the pixel density is so high that the human eye is unable to distinguish individual pixels. Which makes text amazingly crisp and images stunningly sharp.” We all know that iPhone’s smooth flow and easy multi touch nevigation advantage are allwayes being a apple’s USP. This clarity feature will add some more attantion to enhance 3D view with gaming applications.
